Abstract

A dual-mode field programmable RF amplifier/mixer is presented. Transistor switches, low loss CPW lines and RF transistors are combined in a 3-stage distributed topology which can operate as either a distributed amplifier or a distributed mixer. Functional reconfigurability is achieved using one bit programming without changing the signal path. The programmable module in its distributed amplifier mode provides a gain of 8 dB in a 3-8 GHz bandwidth. When switched to the distributed mixer mode, it shows a measured average conversion gain of 4 dB in a 1-16 GHz bandwidth. This circuit is fabricated in a standard 130 nm CMOS technology and occupies 4 mmtimes1.2 mm chip area.
